python-3.x - 我在网络的边缘x 我需要的颜色不止一种
问题描述
Bokeh 和 networkx 在其文档中的示例正在运行。我不知道他们使用的数据，所以我使用的是我在下面找到并显示的“空手道俱乐部”数据。我不能假设这是相同的数据。我从 json 文件中读取数据。
import networkx as nx
import json
from bokeh.models.graphs import from_networkx
from networkx.readwrite import json_graph
import holoviews as hv
from bokeh.models import Circle, MultiLine
hv.extension('bokeh')
def read_json_file(filename):
with open(filename) as f:
js_graph = json.load(f)
return json_graph.node_link_graph(js_graph)
G = read_json_file('/Users/Desktop/KCnet.json')
lst_big_nodes = []
i = 0
for lst in list(nx.connected_components(G)):
if len(lst) > 7: # if this connected then all nodes same color
lst_big_nodes = lst
nd_attrs = {}
edge_attrs = {}
for nd, _ in G.nodes(data=True):
if nd in lst_big_nodes:
nd_attrs[nd] = '#f44171'
else:
nd_attrs[nd] = '#4286f4'
nx.set_node_attributes（G，nd_attrs，“g_color”）
IN_LIST, NOT_IN_LIST = "red", "gray" for start_node,end_node, _ in G.edges(data=True): if start_node in lst_big_nodes: # or end_node in lst_big_nodes: edge_color = IN_LIST
else: edge_color = NOT_IN_LIST edge_attrs[(start_node , end_node)] = edge_color
nx.set_edge_attributes(G, edge_attrs, "edge_color")
plot = figure(title="Netwkx", plot_width=1000 ,plot_height=800,
x_range=(-1, 1), y_range=(-1, 1),
tools="pan,wheel_zoom,reset", toolbar_location="above")
graph_renderer = from_networkx(G, nx.spring_layout, scale=1, center=(0, 0))
line_alpha=0.8, line_width=1)
graph_renderer.node_renderer.glyph = Circle(size=8, fill_color="g_color")
graph_renderer.edge_renderer.glyph = MultiLine(line_color="edge_attrs",
line_alpha=0.8, line_width=1)
plot.renderers.append(graph_renderer)
plot.xgrid.grid_line_color = None
plot.ygrid.grid_line_color = None
output_file("interactive_graphs.html")
show(plot)
我得到错误：
nx.set_edge_attributes（G，edge_attrs，“edge_color”）
for (u, v, key), value in values.items(): ValueError: not enough values to unpack (expected 3, got 2)
我确实尝试了很多不同的香草口味，但边缘颜色没有工作代码。我错过了一些东西，我没有看到它。谢谢您的帮助。
函数 read_json_file 来自读取 json graph networkx 文件
